Ac Mains Input Connection; Motor And Mains Connection With Service Switch - Danfoss vlt fcd 302 Operating Instructions Manual

Installation
12, 13 24V DC digital supply voltage. Useable for digital
inputs and external transducers. To use the 24V DC
for digital input common, programme 5-00 Digital I/
2 2
O Mode for PNP operation.
18, 19, 32, 33 Digital inputs. Selectable for NPN or PNP function in
5-00 Digital I/O Mode. Default is PNP.
27, 29 Digital inputs or outputs. Programmable for either
5-01 Terminal 27 Mode for terminal 27 and
5-02 Terminal 29 Mode for 29 selects input/output
function. Default setting is input.
35 Common (-) for external 24V control back up supply.
Optional.
36 External + 24V control back up supply. Optional.
37 Safe Stop. See Safe Stop installation for details.
20 Common for digital inputs. To use for digital input
common, programme 5-00 Digital I/O Mode for NPN
operation.
39 Common for analog output.
42 Analog output. Programmable for various functions
in parameter group 6-5*. The analog signal is 0 to
20mA or 4 to 20mA at a maximum of 500 .
50 10V DC analog supply voltage. 15mA maximum
commonly used for a potentiometer or thermistor.
53, 54 Analog input. Selectable for voltage (0 10V) or
current (0- or 4- 20mA). Closed is for current and
open is for voltage. Switches are located on the
frequency converter control card. See 2.4.13 DIP
Switches
55 Common for analog inputs.
61 Common for serial communication (RS-485
interface). See 2.4.12 Grounding Shielded Control
Cables
68 (+), 69 (-) RS-485 interface. When the frequency converter is
connected to an RS-485 serial communication bus, a
switch on control card is provided for termination
resistance. ON for termination and OFF for no
termination.
62 RxD/TxD –P (red cable) for PROFIBUS. See dedicated
literature (MCA 101) for details.
63 RxD/TxD –N (green cable) for PROFIBUS.
66 0V for PROFIBUS.
67 +5V for PROFIBUS.
B01-B12 B-option. See dedicated literature for details.
G, R, V, N, P Connection of LCP.

2.4.6 AC Mains Input Connection

• •

frequency converter. See the maximum wire size in
the Input Current and Wire tables in section Specifi-
cations.
•
Comply with local and national electrical codes for
cable sizes.
•
Connect 3-phase AC input power wiring to
terminals L1, L2, and L3.

MG.04.F2.02 - VLT is a registered Danfoss trademark
Depending on the configuration of the equipment,
input power will be connected to the mains input
terminals or the input disconnect.
Ground the cable in accordance with grounding
instructions provided in General Earth (Ground)
Requirements.
All frequency converters may be used with an
isolated input source as well as with ground
reference power lines. When supplied from an
isolated mains source (IT mains or floating delta) or
TT/TN-S mains with a grounded leg (grounded
delta), set 14-50 RFI Filter to OFF. When off, the
internal RFI filter capacitors between the chassis
and the intermediate circuit are isolated to avoid
damage to the intermediate circuit and to reduce
earth capacity currents in accordance with IEC
61800-3.
